Diagnose Internet connection problems if you use Wi-Fi
Here are some reasons why Wi-Fi connectivity has been disabled:

- Wireless interference: Nearby Wi-Fi networks can interfere with your network if they use the same frequency channel and if they are nearby. Change the position of the router, and it is recommended to change the frequency channel to 5 GHz if the router supports it.
